This is another simple one to explain, this is simply the keyboard layout that is used for the keyboard. This allows you to define what each key does, and how the layers operate. Most of the time, this takes the form of the characters that the keyboard is going to press, however since...
在上面汇编中,我们定义了GRUB启动需要的域MBOOT_MAGIC、MBOOT_FLAGS和MBOOT_CHECKSUM,并调用了内核入口函数kernel_main, kernel_main下一节实现。 2. 编译生成目标文件boot.o $nasm -f elf boot.asm -o boot.o 运行上面命令后会生成目标文件boot.o,-f elf的意思是生成ELF格式的目标代码。 第二步 内核入口 ...
